Abstract: An aortic valved tube which is used in human implants to replace the corresponding cardiac valve and ascending section of the aorta itself, incorporates a cardiac valvular prosthesis in its proximal end. The valved tube has two integral branches which project from opposite points with an inclination relative to the longitudinal axis of the tube, which branches are for effecting the anastomosis of the ostiums, corresponding to the left and right coronary arteries, respectively. The branches, as well as the sectors above and below the branches, are reinforced by a thicker wall in those areas while, maintaining the inside diameter of the tube itself.

Abstract: The artificial heart is designed for intrathoracic implantation, while its operation is effected by means of an extracorporeal control and energy feed system, form by a reduced console and interchangeable energy sectors and pneumatic sectors, also interchangeable, all of this taking up a minimum volume susceptible to being carried by the patient himself. Said heart is destined to a half life use and is based on a tubular-valved system, eliminating the classic heart chambers. The artificial heart utilizes a left sector and a right sector couplable between the left auricle and the aorta and the right auricle and pulmonary artery, respectively, sectors divided into compartments by means of cardiac valvular prostheses for the left sector and for the right sector.

Abstract: The support consists of an architectural functional unit made up of modules articulable in such a way that the unit is to be fixed to one of the branches of the sternal separator which is placed in the patient. Structurally the support includes a section (1) for securing the sternal separator from whose section a first module made up of a tube (3) and a telescopic rod (4) immovable by a radial screw (5) emerges. This module is followed by another one made up of a tube (7) joined to the end of the rod (4), tube which is a rotation support for a fourchet (8) to whose side branches grooved sections (9) through which grounds of suture thread (23) pass are fixed. The ends of the fourchet (8) bear a rotating tube in which a rod (15) to which the prosthesis itself (17) is secured is mounted in an inclined manner and a middle piece (18) is inserted.

Abstract: A metallic cardiac valve prosthesis having an aortic as well as a mitral application, the purpose of which is to obtain an ample, highly physiological and laminar flow of blood, includes a ring, the outer contour of which is circular and the inner contour of which is oval. The interior of the ring is provided with a lenticular plug acting in the same way as the plug of a butterfly valve.
